So simple, so quick and so delicious. Add a little coffee liqueur if it takes your fancy.
Preparation time:5 - 10 minutes
If the sponge is difficult to swallow, use a little extra coffee to soak and soften. You can also try without the sponge (the ice-cream, coffee and milk froth are still lovely on their own). If you prefer, use decaffeinated coffee (caffeine can stimulate the bladder).
